(Ubi Gadung) tuber from Terengganu, Peninsular Malaysia. Journal of Agricultural Technology 8(5): 1855-1865. The allelopathic effects of water extract and methanol crude extract from Dioscorea hispida Dennst. (Ubi gadung) tuber was tested on the seeds of selected crops in petri dishes. Experiments were conducted to determine the effects of water extract and methanol crude extract on the germination, radicle length and fresh weight of bioassay test species; namely maize (Zea mays), mustard (Brassica sp.), cucumber (Cucumis sp.), spinach (Amaranthus sp.) and radish (Raphanus sp.). The results showed that the water extracts gave significant effects on germination rate and radicle length of these bioassay species. The water extract strongly inhibited the germination and radicle length of mustard (Brassica sp.) at 12.5 g/L and 50.0 g/L concentrations. Besides, the concentration of water extract at 25.0 g/L inhibited the germin...

The wax apple trees were spray treated with 0, 5, 10 and 20 mg L-1 NAA under field conditions during 2008 to 2011. The experiments were carried out in Completely Randomized Design (CRD) with six replications. Leaf chlorophyll content, chlorophyll fluorescence, photosynthetic yield, net photosynthetic rate, drymatter content of leaves and total soluble solids and K+content of wax apple fruits were significantly increased after treatments with 10 mg L-1. Polygalacturonase activity significantly decreased with NAA treatments. The application of 5 mg L-1 NAA increased 27% more bud and reduced 42% less fruit drop compared to the control. In addition, higher protein and phosphate synthase activity of leaves, fruit set, fruit growth, larger fruit size and yield were recorded in NAA treated plants. In storage, treated fruits exhibited higher...

In this experiment, there were five irrigation schedules applied on D. hispida: daily watering (T2), watering at one day interval (T1/control), two day intervals (T3), five day intervals (T4) and six day intervals (T5). Each plant was given 440 mL of water in every application. Treatment T2 showed the highest percentage of tuberization (80%), while for T5 no aerial tuber formation was observed. To our knowledge, aerial tuber formation of D. hispida has never been reported until now. Aerial tubers have the potential to be used as an alternative and clean planting material for propagation and if they can be induced to germinate, it would be possible to use them for the tissue culture and commercialization of D. hispida.

In this study, effects of zinc (Zn) on corn plants were studied. Different Zn concentrations(0, 0.2, 1.5 and 3 ppm) were externally applied on plant leaves. Plants' height and leaf numbers were not affected by the application of different Zn applications. Relative water content (RWC) increased gradually with increasing Zn concentration followed by decreased at higher level of Zn application. The net photosynthesis rate (Pn) showed similar to RWC results. Chlorophyll (Chl) content increased in Zn-treated plants than Zn-untreated plants but Chl fluorescence increased only at higher Zn concentration condition. Zn application increased yield compared than control but did not differentiate among Zn treatments. Taken together, it seems that Zn at 1.5 ppm as foliar applicationshowed better result in terms of production and physiology of corn plants.

In order to evaluate the effects of copper on corn production, an experiment was conducted in the field. In this study, the effects of Cu on corn production were studied with regard to plant parameters, relative water content (RWC), chlorophyll (Chl) content, chlorophyll (Chl) fluorescence, photosynthesis parameters, and yield parameters. Different Cu concentrations (0, 0.2, 1.5 and 3 ppm) were applied as a foliar spray on leavesof corn plants. Plants’ height wasinduced by the application of different Cu applications (1.5 and 3 ppm) but not on leaf numbers. Relative water content (RWC) increased gradually with increasing Cu concentration. On the other hand, net photosynthesis rate (Pn) and photosynthetically active radiation (PAR)decreased with increasing Cu concentration. Chlorophyll (Chl) content increased in leaves of Cu-treated plants than Cu-untreated plants andChl fluorescence ...

Results revealed that fruits of both Masam manis (pink) and Jambu madu (red) cultivars are the ultimate sources of anthocyanin, carotene and vitamin-C. On the contrary, chlorophyll and titratable acidity content were higher in fruits of Giant green (green) cultivar. The amount of trace elements was high in pink followed by red and green cultivars. The highest amounts of total phenols and flavonoids were in methanol extracts compared to ethanol fruit extracts and these polyphenolic compounds were correlated with antioxidant activities (R 2 = 0.98). In addition, ethanol extracts of leaf, bark and fruit showed good antioxidant activity with IC 50 values ranging from 283-358 µg mL -1 and antimicrobial activity as compared to methanol extracts. Among the cultivars, red cultivar performed the best antimicrobial activity. Bark and fruit extracts of ...

Flower growers have a lot of interest in making flower enlargement and shorten longevity to harvest flower earlier and to make it marketable soon. Gibberellic acid (GA3) and aluminium sulphate Al2(SO4)3 play significant roles in flower enlargement and development. Hibiscus sp. was used in this experiment. The branches were dripped with the respective chemical [GA3 and Al2(SO4)3 100 ppm] at 3 days interval for 3 weeks. It had been shown that the 100 ppm GA3 played major role in developing a bigger size of the flower, production of more leaves, shorter longevity of flower, quicker bloom and greater size and weight of the flower as compared to the Al2(SO4)3 and control. Chlorophyl content (represented by SPAD value) and fluorescence were higher in GA3 treated branch than in aluminium sulphate treated branch and control. The quantum yield (Fv/Fm) was maximal in GA3 treated branch. The aluminium sulphate treated branch also showed the similar results but the longevity of the flower had the longer duration in aluminium sulphate treated branch than in GA3 but shorter than control. The results showed that these two chemicals [GA3 and Al2(SO4)3 100 ppm] using dripping technique instead of spray were effective for the enlargement of flower size and shorten the flower longevity with less chemical cost and quantity of chemicals without hazarding the environment instead of spray. In addition, it improved the weight and increased the blooming rate and could be acceptable to the flower growers easily and could be harvested for commercial purposes earlier.

Some of varieties shared similar characteristics and some of the collections (accessions) showed intermediate characteristics. In Ficus deltoidea varieties, not only var. bilobata had lobed leaves, other varieties such as var. kunstleri and var. trengganuensis also have emarginated and lobed leaves. Studying monophyly of F. deltoidea var. bilobata based on molecular and morphological data will give more information to taxonomist and farmers. Previous study was about morphology data alone. In this study, a phylogenetic relationships between F. deltoidea var. bilobata, var. trengganuensis, var. kunstleri and one outgroup which is var. motleyana were examined by using cladistic analysis, based on morphological data with the support of molecular data. Three primer regions which are ITS, ETS and G3pdh were used to obtain molecular data and 27 characteristics were observed for morphological data. Var. bilobata was not monophyly and the position of tested var. bilobata based on the morphological and molecular data was scattered either in individual or combined trees. The pioneer taxonomist in publishing a well-documented work about Ficus deltoidea is Corner [1]. F. deltoidea in Peninsular Malaysia is classified into seven varieties. Seven varieties of F. deltoidea were described namely var. deltoidea Corner, var. bilobata Corner, var. angustifolia (Miq.) Corner, var. intermedia Corner, var. kunstleri (King) Corner, var. motleyana (Miq.) Corner and var. trengganuensis Corner that were found in the Malay Peninsula [2]. Some of the varieties share similar characteristics and some of the collections show intermediate characteristics [1], thus causing confusion to recognize and differentiate between varieties.

Moench) under BRIS soil condition. The field experiment was conducted during July, 2014 to April, 2015 at the teaching and research farm of University Sultan Zainal Abidin (UniSZA), Besut Campus, Terengganu. Performance of okra variety Singa 979 was assessed by application of NPK at different rates (0 kg ha-1 (control), 150 kg ha-1 , 170 kg ha-1 , 190 kg ha-1 and 210 kg ha-1. The treatments were fitted in a randomized complete block design (RCBD) replicated thrice. Data collected for growth and yields performances included plant height, number of leaf/plant, leaf area, number of branch/plant, chlorophyll content, photosynthesis rate, transpiration rate, internal CO 2 , stomatal conductance, number of flower/plant, number of pod/plant, weight of pod, number of seed/pod and total soluble solid (TSS) of the pods. Based on the results obtained from this experiment, application of NPK at the rates of 190 kg ha-1 and 210 kg ha-1 shows the highest growth and yield performance. It is followed by application of 170 kg ha-1 and 150 kg NPK/ha-1 in decreasing manner. No application of NPK shows the lowest growth and yield response. The significance of this research was to study the minimum rate of NPK on the effect on okra ground around the sea shore of Terengganu or in BRIS soil
